Just an hour's boat trip away from Cartagena lie the magnificent Rosario Islands, which belong to Colombia's only underwater natural park (Rosario and San Bernardo Corals National Natural Park). Abundant marine wildlife (including over 50 species of corals) and some of Colombia's best beaches draw in many in search of relaxation and active pursuits such as snorkelling and diving. Isla Grande is best for kayaking through unique mangrove forests and seeing the phosphorescent plankton light up the waters of a brackish lake at night, while Playa Blanca is Cartagena's most spectacular white-sand beach (also reachable by land). It should be said that the company you choose to tour with has the potential to make or break the experience. Low cost tours can mean multiple intermediate stops en route to your destination, as well as unpleasant surprises such as no transfer back to your hotel. Try and choose a trusted company with consistently good reviews, or opt for a private tour. Mind that seas may be rough at certain times of the year, particularly in December and January, when tours on smaller boats may even become dangerous.

Stroll around in the heart of Seville and enjoy the charm of the quarter of Santa Cruz, with its winding alleys, picturesque houses and small squares. This is also where you can see important tourist attractions like the Cathedral, the Giralda, the Royal Alcázar, the Murillo gardens and the Archivo de Indias.

A national monument of France, this Roman Catholic cathedral, dedicated to Saint Peter, was originally founded as a church in 1364 and later became a cathedral in 1536. The architectural marvel is built in the Gothic style and captivates visitors with its stunning features, including beautiful stained glass, old religious paintings, and an attached garden.
